Do you have any plans to change Turkey's name? Because it's the official name now.

In addition to what other commenters have said: this database uses the English language; labels for other languages are a matter of localization. As there is no language academy or other legal authority for English, there is no such thing as "official" in English, and it has long been the policy of the maintainers of the database to follow customary English usage. So if the government of a country wants the database to refer to it (or a location within it) by a different name, it first must convince the community of English speakers to do so in ordinary writing. -GAWollman
